A Swirl-Driven Grouting Control Method for Non-Newtonian Fluids: 2.5D Seepage Model and Stability Analysis of Fractal-like Viscous Fingering

In porous media grouting, highly viscous non-Newtonian fluids often trigger viscous fingering (Saffman–Taylor instability) due to adverse mobility ratios, creating fractal-like preferential channels that severely weaken the reinforcement volume. To overcome this, a novel swirl-dr...

Experimental Study on the Physical and Mechanical Properties of Loess Improved by an LM-1 Curing Agent and Cement Composite

This study focuses on loess in the Lanzhou region and employs a self-developed LM-1 ionic cementitious curing agent (mainly sodium silicate) combined with cement for loess improvement. Through mechanical tests, X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) analysis,...
